Machine Guns & Automatic Firearms in Maine

Maine law prohibits knowingly possessing a machine gun; however, this prohibition does not apply to machine guns manufactured, acquired, transferred, or possessed in accordance with federal law.1

Federal law requires machine guns to be registered with the Bureau of Alcohol, Tobacco, Firearms & Explosives (ATF), and generally prohibits the transfer or possession of machine guns manufactured after May 19, 1986.2 In December 2018, ATF finalized a rule to include bump stocks within the definition of a machine gun subject to this federal law, meaning that bump stocks will be generally banned as of March 26, 2019.3
